Abstract

A magnetic field shielding layer that does not affect an operation of a geo-magnetic sensor in a pointing input device of a touch screen type using an electromagnetic pen is provided. A magnetic field shielding layer is composed of magnetic metal powder. The magnetic field shielding layer is formed directly on the pointing input device without a need for a separate adhesive layer.
